Picture Perfect: Using Drone Technology and Photogrammetry Techniques to Map the Western Stone Forts of Ireland

ABSTRACT The Western Stone Forts form some of the most spectacular archaeological monuments in Ireland and include well known sites such as Dún Aonghasa in Co. Galway and Cahercommaun in Co. Clare. The group comprises a number of heterogeneous forts characterized by their exceptionally thick and high stone walls and other distinctive architectural features such as terraces, steps, guard chambers, and chevaux de fries. It is clear, however, that they form a loosely defined group of monuments that have a broad chronological span ranging from the Late Bronze Age to the Early Medieval period. The aim of this project is to create a complete suite of high resolution three-dimensional models of the Western Stone Forts on the Tentative List of UNESCO World Heritage Sites, and assess the applicability of photogrammetry techniques to landscape studies and heritage management.
